The Charm City Inc Must Select Among A Series Of New Investment Al

1. The Charm City Inc. must select among a series of new investment alternatives. The potential investment alternatives, the net present value of the future stream of returns, the capital requirements, and the available capital funds over the next three years are given below: Net Present Value ($), Capital Requirements ($), and available capital funds over three years.

Investment alternatives include: Warehouse expansion, Test market new product, Advertising campaign, Research & Development, and Purchase new equipment. The company has a total capital fund of $110,750 available over three years and wants to select at least three alternatives. Additionally, it wants to select at least two alternatives from the warehouse expansion, research & development, and purchase new equipment options.

The challenge is to develop a capital budgeting problem formulated to maximize the total net present value under the given constraints. The formulation should include decision variables, the objective function, and all relevant constraints. The formulation should be comprehensive and precise, without solving the problem.

Formulation of the Capital Budgeting Problem for Charm City Inc.

To maximize the net present value (NPV) from the selection of investment alternatives subject to capital constraints and strategic preferences, we define the problem variables as follows:

  • Let \( x_i \) be a decision variable indicating whether investment alternative \( i \) is selected (1) if selected, 0 otherwise, for \( i=1,2,3,4,5 \).

The specific alternatives are numbered as follows:

  1. Warehouse expansion
  2. Test market new product
  3. Advertising campaign
  4. Research & Development
  5. Purchase new equipment

Parameters for each alternative include:

Alternative NPV ($) Capital Requirement ($)
Warehouse expansion 30,000 40,800
Test market new product 92,000 82,000
Advertising campaign 40,800 33,900
Research & Development 82,000 40,800
Purchase new equipment 33,900 82,000

The main goal is to maximize the total NPV of selected investments, expressed as:

Objective Function:

\[

\text{Maximize} \quad Z = 30,000x_1 + 92,000x_2 + 40,800x_3 + 82,000x_4 + 33,900x_5

\]

Subject to the following constraints:

  • Capital constraint:
  • \[
  • 40,800x_1 + 82,000x_2 + 33,900x_3 + 40,800x_4 + 82,000x_5 \leq 110,750
  • \]
  • Number of investments:
  • \[
  • x_1 + x_2 + x_3 + x_4 + x_5 \geq 3
  • \]
  • At least two from specific group:
  • \[
  • x_1 + x_4 + x_5 \geq 2
  • \]
  • Binary decision variables:
  • \[
  • x_i \in \{0,1\} \quad \forall i=1,2,3,4,5
  • \]

Thus, the formulated binary integer programming model aims to maximize total NPV while adhering to capital constraints and strategic investment choices, without solving the model explicitly.

2. Lease Decision for Jodi: Optimal Choice Using Different Criteria

Decision Criteria and Profits for Each Dealer

Dealer 10000 Miles 14000 Miles 18000 Miles
A $7,000 $10,500 $13,500
B $8,500 $11,500 $11,000
C $10,000 $9,500 $9,800

Jodi considers three scenarios: driving 10,000, 14,000, or 18,000 miles annually, with associated profits from each lease option. Her objective is to determine the best leasing option using the following decision criteria:

  1. Maximax
  2. Maximin
  3. Equal likelihood
  4. Minimax regret

a. Decision Using the Maximax Criterion

Maximax selects the alternative with the highest possible profit across all scenarios, focusing on the optimistic outlook.

For each dealer, identify the maximum profit:

  • Dealer A: max is $13,500
  • Dealer B: max is $11,500
  • Dealer C: max is $10,000

Decision: Lease from Dealer A, with a profit of \$13,500.

b. Decision Using the Maximin Criterion

Maximin chooses the option with the best of the worst-case profits, emphasizing caution against unfavorable scenarios.

Minimum profit for each dealer:

  • Dealer A: \$7,000
  • Dealer B: \$8,500
  • Dealer C: \$9,500

Decision: Lease from Dealer C, with a minimum profit of \$9,500.

c. Decision Using Equal Likelihood and Expected Value

Assuming each scenario has a probability: P(10,000 miles) = 0.5, P(14,000 miles) = 0.3, P(18,000 miles) = 0.2, calculate expected profits:

  • Dealer A: \( 0.5 \times 7,000 + 0.3 \times 10,500 + 0.2 \times 13,500 = 3,500 + 3,150 + 2,700 = \$9,350 \)
  • Dealer B: \( 0.5 \times 8,500 + 0.3 \times 11,500 + 0.2 \times 11,000 = 4,250 + 3,450 + 2,200 = \$9,900 \)
  • Dealer C: \( 0.5 \times 10,000 + 0.3 \times 9,500 + 0.2 \times 9,800 = 5,000 + 2,850 + 1,960 = \$9,810\)

Decision: Lease from Dealer B, with the highest expected profit of \$9,900.

d. Expected Value of Perfect Information (EVPI)

EVPI measures the value of knowing future states with certainty. It is calculated as:

\[

EVPI = \text{Expected Profit with perfect information} - \text{Expected profit under current decision}

\]

Under perfect information, Jodi would choose the dealer with the highest profit for each scenario:

  • 10,000 miles: Dealer C (\$10,000)
  • 14,000 miles: Dealer B (\$11,500)
  • 18,000 miles: Dealer A (\$13,500)

Expected profit with perfect information:

\[

0.5 \times 10,000 + 0.3 \times 11,500 + 0.2 \times 13,500 = 5,000 + 3,450 + 2,700 = \$11,150

\]

Using expected profit with current strategy (Dealer B, \$9,900), EVPI = \$11,150 - \$9,900 = \$1,250.
